Specification of Letters Patent.

Patented July 11, 1922.

Application led August 2, 1919. Serial No. 314,814.

T 0 all r11/rom t may concern: p

Be it known that I, EDWARD J. KUKAC, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Molds, of which the following is aspeciiication.

My invention relates to new and useful improvements in molds, and has for its object the provision of a device wherein the mold is permanently cast.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed,

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Fig. 1 is a perspective view of my invention.

Fig. 2 is a longitudinal vertical sectional view taken on substantially line 2 2 of Fig. 1.

Fig. 3 is a top plan view taken on substantially line 3-3 of Fig. 2.

Fig. 4 is a sectional view taken on substantially line l-4 of Fig. 2.

Fig. 5 is a perspective view of the casting.

My invention is designed for use in lead casting, and primarily for use in casting terminals for storage batteries. The approved form of construction consists of two metallic blocks 5, hingedly connected at one side, as at 6, so as to permit two of the faces of the blocks 5 to lie throughout their entire length in close engagement with each other. Cast in the faces which lie in close engagement with each other, is a mold or matrix 7, one half of which is cast in each of the members 5. The terminal 8, for the casting of which this device is primarily designed, has openings 9 and 10 extending therethrough. Suitable tapered cores 9 and 10 are provided for the forming of these passages through the terminal.

The core 10 is inserted through the upper face of one of the members 5, and the core 9 is inserted in a groove provided in the faces of the members 5 which lie in engagement with each other. Provided upon one of the faces of one of the members 5 are suitable studs 11, which are adapted to seat in slots l1 provided in the adjacent face of the cooperating element 5, the purpose of the studs ll being to prevent relative lateral motion of the members 5 when in operative position. Projecting from the free ends of the members 5 are suitable handles 12, the outer endsl3 of which are turned at right angles toward each other. These handles 12 are made of some spring metal, the outer ends of the parallel portions being inclined toward each other. A sleeve member '14 is provided for locking the' device in operative position, the sleeve 14 being thrust over the members 12 and slid toward the members 5, locking the same closely together. By forming the members 12 of a resilient material, the members 5 are allowed a certain amount of freedom for vertical relative movement upon the pouring of the molten lead into the matrix. An ingate 15 is provided which commiinicateswvith the matrix in the ordinary manner.

I am aware that devices have been constructed wherein the mold is permanently formed therein, but in this device the mold is cast. The device is intended primarily for use where a fine finish is not necessary on the casting. No machining is necessary, as in the devices which are now ordinarily used, and consequently, a device is produced which is eicient for the purpose designed and very economical in its structure.

l/Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of the construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention, what I claim as new and desire to secure by Letters Patent, is

1. A mold adapted for casting storage battery terminals comprising a pair of hingedly connected co-operating blocks; a matrixin the co-operating faces of said blocks; a removable core positioned through one block substantially at the central portion thereof and extending into said matrix; a second removable core in said matrix, said second core being tapered and located longitudinally in the meeting faces and within the end walls of said blocks; and an exterior opening communicating with said matrix.

2. A mold adapted for casting storage battery terminals comprising a pair of hingedlyconnected (Jo-operating blocks; a removable core positioned through one block substantially at the central portion thereof, extending into said matrix and engaging the second block; a second core in said matrix, located longitudinally Within the meeting faces thereof; handles of resilient material iXedly mounted on said blocks; and locking mea-ns for said resilient handles whereby said elements are yieldingly held in position.

3. A mold adapted for casting storage battery terminals comprising a pair of hingedly connected (zo-operating blocks; a matrix formed inthe meeting faces of said blocks, comprising a cylindrical opening and an adjoining semi-circu'lar opening formed in each of said faces; a core removably carried by one of said blocks and positioned at the central portion of said cylindrical openings; a second core removably positioned at the center of said semi-circular openings; an exterior opening communicatingrvvith said matriX, and means including resilient handles 'for yieldingly locking said blocks in posi-
